Cannulas
For left and/or right sided support for failure to wean, Abbott Medical recommends the CentriMag
TM
Drainage (Venous) Cannula (34Fr)
and Return (Arterial) Cannula (24Fr). Other equivalent commercially available venous and arterial cannula may be used at the
preference of the clinician.
For central cannulation, it is advisable to use cannulas that are wire-reinforced to resist kinking. The drainage cannula should be
malleable so that it will hold its shape after introducing a bend. For ventricular cannulation, the drainage cannula may not need to
be bent. Placing an approximately 90º bend in the cannula may help with atrial cannulation.
